UPK 45 ve UPK 185 Açık Yıldız Kümelerinin Fotometrik ve Tayfsal İncelenmesi

Abstract

Bu çalışmada UPK (Ulsan Pusan Korea) kataloğundan UPK 45 ve UPK 185 açık yıldız kümelerinin (AYK) tayfsal ve fotometrik üyelik analizleri yapılmıştır. Üyelikler ve kümelere ait yaş, uzaklık, kızarma belirlenirken GaiaDR3 asterometrik veriler kullanılmıştır. Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) DR9 tayfsal verileri kullanılarak UPK 45 ve UPK 185’in üye yıldızlarının etkin sıcaklık ($T_{\rm eff}$), yüzey çekim ivmesi ($logg$), ortalama metalisite ($[Fe/H]$) değerleri elde edilmiş ve Gaia sonuçlarıyla karşılaştırılmıştır. Küme üyesi yıldızlar Transiting Exoplanet Survey Satellite(TESS) verileri kullanılarak değişen yıldız analizi yapılmış ve bu yıldızlar değişen türlerine göre sınıflandırılmıştır.
